Abstract

Based on the idea of no hit zone (NHZ) in frequency hopping (FH) systems, new sequences with three no hit zones (T-NHZ) in time-frequency hopping (TFH) systems are presented. With the T-NHZ in the time- frequency (TF) correlation functions, the proposed T-NHZ sequences can be directly employed in time-frequency hopping code division multiple access (TFH-CDMA) communication systems to reduce or eliminate multipath interference. Simulation results show that T-NHZ sequences can achieve much better bit error performance than the NHZ sequences and the traditional FH sequences.
